Electric Hard Seal Wafer Butterfly Valve
Introduction:
The electric wafer type metal hard sealing butterfly valve adopts a three eccentric structure. The sealing surfaces of the valve seat and disc plate are made of different hardness and stainless steel. It has good corrosion resistance and long service life. The valve has a two-way sealing function. The product meets the national GB/T13927-92 valve pressure test standard. The electric wafer type metal hard seal butterfly valve adopts precise J-shaped elastic seal ring and three eccentric multi-level metal hard seal structure, and is widely used in metallurgical, electric power, petrochemical, water supply and drainage, municipal construction and other industrial pipelines with medium temperature ≤ 425 ℃ for flow regulation and fluid carrying. The valve adopts a three eccentric structure. The sealing surfaces of the valve seat and disc plate are made of different hardness and stainless steel. It has good corrosion resistance and long service life. The electric hard seal butterfly valve has a two-way sealing function. The product complies with the national GB/T13927-92 valve pressure test standard.
Structural characteristics:
The valve adopts a three eccentric sealing structure, with almost no wear on the valve seat and butterfly plate, and has the sealing function of tightening as you look. The seal ring is made of stainless steel, which has the double advantages of metal hard seal and elastic seal. It has excellent sealing performance, corrosion resistance, long service life, etc. regardless of low temperature and high temperature. The sealing surface of disc plate is made of hardfacing cobalt based hard alloy, which is wear resistant and has a long service life. Large butterfly plates are made of quilted frame structure, with high strength, large flow area and small flow resistance. The valve has a two-way sealing function, and can be installed in any direction without the restriction of medium flow direction or the influence of space position.
